Field strengths from fixed transmitters, such as base stations for radio (cellular/
cordless) telephones and land mobile radios, amateur radio, AM and FM radio
broadcast and TV broadcast cannot be predicted theoretically with accuracy. To
assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength
in the location in which the Sapphire pump is used exceeds the applicable RF
compliance level above, the pump should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such
as re-orienting or relocating the pump.
4.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than
3 V/m.
Recommended Separation Distances from Mobile RF Communication
Equipment
The pump is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer/pump user can help prevent
electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the pump, according to
the maximum output power of the communications equipment.
The following table provides recommended separation distances between portable
and mobile RF communication equipment and the pump (for life-supporting
equipment and systems).
For transmitters rated at a maximum output power not listed in the table, the
recommended separation distance
d
in meters (m) can be determined using the
equation applicable to the frequency of the transmitter, where
p
is the maximum
output power rating of the transmitter in watts (W) according to the transmitter
manufacturer.
